Abstract

To the Editor: Dr Olshansky's research letter on the accelerated aging of US presidents concluded that presidents do not age faster than other men. 1 That may be true, but this study cannot demonstrate it due to a faulty comparison.Olshansky compared presidents' actual age at death (adjusted for aging by subtracting 2 days for every day in office) against average life expectancy for men matched to the date of inauguration.However, the correct comparison is with men who have the same profile of risk factors for premature death.For example, as Olshansky notes, education, wealth, and access to medical care strongly influence life expectancy, and these factors undoubtedly contributed to longer lives for many presidents.The real question is if, despite these advantages, presidents' lives were shortened.That requires comparison with other men of similar education, wealth, and access to medical care, and possibly with similar risk factors, such as smoking and alcohol consumption.Absent data permitting proper restriction, stratification, or control for confounding, the only conclusion that can be drawn is that presidents tend to be blessed with certain advantages that allow them to outlive men without those advantages.

  • Of these patients, 84 received right heart catheterizations due to suspected pulmonary hypertension, and 55 (10.4%) were diagnosed with pulmonary hypertension based on a mean pulmonary artery pressure >25 mm Hg.

    “Of these patients, 84 received right heart catheterizations due to suspected pulmonary hypertension, and 55 (10.4%) were diagnosed with pulmonary hypertension based on a mean pulmonary artery pressure >25 mm Hg.”

    From Pathophysiology of Sickle Cell Disease (2019) · cites this paper as [194]

    The Results report that 84 of 531 patients underwent right heart catheterization and 55 had pulmonary hypertension, representing 10.4% of the total population. The Methods link catheterization to clinical suspicion but define pulmonary hypertension as mean pulmonary artery pressure of 25 mm Hg or greater, not greater than 25 mm Hg. (LLM, conf=0.90)

  • The NIH-PH cohort study screened 531 patients and followed them for a median of 4.4 years.

    “The largest study with the longest follow-up is the NIH-PH cohort study, which screened 531 patients and followed them for a median of 4.4 years (66, 194).”

  • Among the group with pulmonary hypertension, 56.4% had precapillary pulmonary arterial hypertension with a pulmonary artery occlusion pressure ≤15 mm Hg, and the remainder had pulmonary venous hypertension with elevated pulmonary artery occlusion pressures >15 mm Hg.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
